According to Abiogenesis, life originated from:

Options

A. Non-living matter
B. Pre-existing life
C. Oxygen
D. Extra-terrestrial matter

Explanation

**Step-by-Step Solution:**

1. **Understanding Abiogenesis**: The term "abiogenesis" can be broken down into two parts: "a-" meaning not or without, and "biogenesis" meaning life. Therefore, abiogenesis refers to the origin of life from non-living matter.

2. **Definition of Abiogenesis**: According to the theory of abiogenesis, life originated spontaneously from non-living matter. This means that life did not come from pre-existing life forms, but rather arose from simple organic compounds or other non-living substances.

3. **Spontaneous Regeneration**: Abiogenesis is also known as spontaneous regeneration. This term emphasizes the idea that life can arise naturally from non-living materials without any external intervention.

4. **Evaluating the Options**: The question provides four options:
- Non-living matter
- Pre-existing life
- Oxygen
- Extraterrestrial matter

- **Non-living matter**: This aligns with the definition of abiogenesis.
- **Pre-existing life**: This contradicts the concept of abiogenesis, as it suggests life comes from life.
- **Oxygen**: While oxygen is a non-living element, it does not represent the source of life according to abiogenesis.
- **Extraterrestrial matter**: This implies that life came from outside Earth, which is not the premise of abiogenesis.

5. **Conclusion**: The correct answer is that according to abiogenesis, life originated from non-living matter.

**Final Answer**: Non-living matter.
